adjust your vnt maps properly, thats was the problem. i can see it in your logs.
I tried that with lower values and than with higher values...but there is always same problem.
I'm totally out of idea what to try next and not sure what is going on. Is values in VNT maps for 2000-2200 RPMs to high so after that ECU drops boost, or there is noting wrong at that range, but is wrong in 2200-2600 RPM range?
I'm logging with bluetooth dongle and mobile phone (AlfaOBD), and values in logs are received one after another, there is a some time difference between them. So, if in logs is value 2500 for RPM and let say 2200 mbar boost, this boost is actually for RPMs higher than 2500. Same thing with n75 values.
Other thing, when I put pedal to the metal, sport n75 map is activated and there are lower values than in eco n75 map. I don't know how much time needs to pass (with WOT) to return to eco n75 map. When accelerating from low revs (1600-1700 RPMs) with WOT, while engine reaches 2200 RPMs ECU should already switch to eco n75 map. And in that map, at 2000-3000 RPM range there is no fluctuation of values...they are dropping with REVs.
So, please, instead of only saying that this or that map should be adjusted, can someone describe what is acctualy happening here?
I know that many different things can cause this, (lower injection time than expected, lower or higher boost than expected, IQ limiter by airflow or RPM, SOI)...but something should came first and after that all other parameters go low. Question is now...what is first parameter that goes out of expected value?
Somewhere I found that VNT maps are used only under some RPMs and after that VNT switches to closed loop mode. Is that somewhere around 2500RPMs so maybe this can cause this boost drop?
